Firefox Support Forum

I updated to the latest version yesterday and now my Bookmarks ,History and a few other things have gone into Dark Mode. I really don't care for it and have tried looking into my settings but I see nothing that I can do to go back to the normal white. I am using Windows 11 on an HP All In One Desktop computer. Is there anything I can do to revert back to the way it was? Thanks for any reply.

I made a post the other week about issues I was having with Firefox & YouTube.

Having put the browser in safe mode I discovered that it was my ad blocker/s. That said, I had notice Firefox lagging or loading hard on video sites, not just YouTube as well as some applets on other sites. And having experimented with various ad blockers and video sites as well as my own blogs, I find that I am not having these problems with ad blockers in Chrome or Edge, but only Firefox, so much so, that most of these sites are entirely unusable unless I disable the ad blocker/s in Firefox.

Frankly, I've been noticing it for some time, but as of the other week they have nearly rendered the browser unusable, or the ad blocker/s unusable in Firefox on said sites. I have completely uninstalled and reinstalled the add-ons, from the Mozilla site, to no real avail.

It is not only annoying but very frustrating and I am about to give up, on the browser altogether. I am not having these problems with the same ad blocker/s in Chrome.

I've spent nearly two weeks on this and it hasn't gotten better.

There it is. Thank you.

Tried to reset settings. Does not work. Went to about:config, than tab.mo / print.tab_modal.enabled set to false. Did this method before and it worked. Now this method does not work trying to get print preview back. Firefox is my web browser. I am in windows 8.1. Seems like Firefox did some updates again and now I can not get print preview back! WHY DOES NOT FIREFOX LEAVE WILL ENOUGH ALONE WHEN THEY HAVE SOMETHING GOOD? Bring back the old classic print preview button back and leave it. Now how can I get the old print preview button back???? Need help!! Thanks philm

I noticed today that all my color PDFs are viewing as black and white. For years they were fine, presenting as color. This is a serious problem, as I am a graphic designer and have many PDFs on my portfolio. I am also seeing the same problem with PDFs linked to my clients' sites.

Images on PDFs are still in color. It's the flat color graphics created in InDesign exported to PDF. Oddly enough, gradients (originally created in InDesign as well) are still presenting as color, but only the gradients.

I do not have this problem in Safari, nor in other browsers, but Firefox has been my go-to browser for years. I never had a problem until I noticed today. Firefox updated two days ago. I'm on a Mac and I now have Firefox version 102.01, as it updates automatically.

Thank you for attending to this issue.

This happened after the last update 105.0. Any way to fix it?

I have google set as my homepage and cursor starts at the address bar when opening firefox instead of the google search box in the middle like it always did.

106.0.2 locks up Windows Explorer (Not Responding) on my Win 7 machine as soon as it starts. After restarting Explorer, it seems to continue working. I have seen this issue reported earlier.

I just updated last night to version 98.0 of Firefox, and have noticed that when I click on manage bookmarks that the boomarks now open at the bottom of the various bookmarks folders by default instead of opening at the top like they used to. What happened here? I am including a picture to show where the manage bookmarks section is going by default now instead of where it normally does. Can anyone help fix this?

Firefox can no longer play Netflix movies. Firefox loads the Netflix site. Firefox attempts to play the movie. Then, Firefox can't play the movie. Netflix says "Your browser is no longer supported." This happens every time there is a Firefox update! Do you guys not test your products in development before release? Please fix your product. I tried all your 'help' items.

My Firefox browser seems to have reset itself to Windows 8 compatibility. I have Windows 10, 64-bit. Firefox will not open full screen, but opens a tiny, narrow window at the bottom of the screen which I have to use task manager to close. I remember one of the automatic updates coming through a few days ago.

Can I do anything other than uninstalling and a new install? I'd like to keep my favorites list, etc. I am at the extent of my computer skills with this.

When I download a file before I even have a chance to save or open the file Firefox downloads the file and puts it on my desktop. I have to look at lots of .pdf files and this a bit annoying as I have to keep deleting all the files I dont want. The dialog box opens and I always choose open rather than save but Firefox has already saved a copy to my desktop. How can I stop this autosave please ? Cheers.

Hello there to anyone who can help me with this problem that I'm having right now. Yesterday while watching and going through the videos on youtube, while watching a video, it suddenly started to lag and not move as smoothly much as before when I have on a higher quality like in 1080p 60fps or 720p60fps.

This has happen to me a couple times before when I couldn't find a way to fix it like when my my laptop was acting stupid and was resetting itself and showing a blue screen when it happen and had someone help me take it to the store and have it fixed and the reset my laptop or something and had to go redownload Firefox and I think the problem stopped working.

Yesterday and today I tried searching and looking up how to fix this and find answers that tell me to go to the about:config and change somethings to false or true whatever and it still has this problem. I hope changing it to whatever doesn't mess it up anything even more.

I thought I had to go update Windows or something since recently a couple of times the youtube videos get stuttery and not move as smoothly at times. I can't remember much this one but I either just close Firefox to hopefully that it goes back to normal or I have to update Windows to restart my laptop and it works and it goes back to normal.

But this time when I did all that and I try to update Windows from my laptop it was doing what it does updating installing or downloading yesterday. The problem is still there and the videos on youtube are still stuttering. And I try to see if there were more things to update there was nothing there and says its up to date.

I linked a video that has a 60fps option on a another browser Microsoft Edge to see if it works from there and video when putting it on 60fps works fine there. So this must be a Firefox problem or something.

So if anyone can help me with this problem. Please tell if there's anything else I can do to get these videos on youtube to work on Firefox in 60fps and hopefully can try to easily fix this and hope its nothing complicated to do. Or if there is a bug or something that's making these videos stuttering and everything please try to fix this problem that's going with me right now. Cause i don't want to have to deal with problem I had before again forever and/or if its permanent.

Hopefully maybe the next update for Firefox might fix this problem I have from these youtube videos, but I don't know. Whenever an update for Firefox happens sometimes, the videos on youtube start to stutter and not move as smoothly with putting it on 60fps and have this problem again.

Thank you if anyone has the time to look at this and hopefully someone can get me the answer to finally fix these videos that are freezing stuttering and stuff there.

Hello. Firefox quickly takes up all the space on the SSD. After about two days of work, there is no disk space left. Closing the browser helps, but it's not comfortable. Windows 10 system.

Merely typing an email when the tab and window it was in shut down (am using linux mint and most recent FF build.) I have difficulty understanding programmer directions as typically given but can follow a path > to files and folders. I found firefox old backups and sessions folder but none of the session restore files are dated, won't open and won't restore. I wish there was a straight-forward path to restore "my sessions" when issues develop. Just show me where the file path > where the files are > and what to click. Thank you.

This command doesn't work, and I've seen others with the same issue and no one ever gave a response on how to fix it.

I'm assuming the same thing will happen here, but I just started using Fire Fox and really hope someone can give some resolve.

I tried running with no extensions too, it still didn't work.

Microsoft Edge Control + Shift + N works

Chrome Shift + N works

I tried this solution "Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is is causing the problem. " It didn't work.

Please could someone help me. Firefox has been my favorite go to browser, but now I am forced to look for alternatives.

I'd like to know why my previous question on this matter was deleted.

How do I change the font and line spacing characteristics?

Specifically, my tabs are now 4 pixels too high and the menu font spacing is also 4 pixels too high.

This has made the dropdowns for my bookmarks bigger than my screen (for example) and I find that I'm needing to move the mouse excessively from the extra space introduced when I right click on a page for menu options there as well.

I updated my Firefox today and now videos do not play.

I had this problem back in April after an update and I spent weeks troubleshooting it. Eventually I got it to work after trying all of the following (then, and again now):

Things I've Tried: 1.) Clearing data (cache and cookies) 2.) Turning off "Strict Mode" 3.) Running CCleaner 4.) Disabling/enabling HW acceleration 5.) Checking that the DRM box is checked (and trying it without it checked) 6.) Refreshing Firefox 7.) Uninstalling/Reinstalling 8.) Updating my Windows install 9.) Updating drivers 10.) Disabling all Firefox extensions 11.) Running without extensions 12.) Running in Firefox Troubleshooting Mode 13.) Running Windows in Safe Mode with Networking 14.) Running a fresh install of Firefox without signing in after deleting all traces of Firefox from my PC (including Program Data folders, registry entries, etc.)

What finally worked back in April was to dive into "about:config" and change "media.rdd-processenable" to "false".

That fix does not work this time around.

In the meantime I've been using Brave and having no issues. I've tried video playback in Chrome, Opera, and Edge on this computer with no issues. This playback problem is exclusive to Firefox.

Video playback still works just fine on my 4 home PCs running Windows 10 and Pop_OS (3 self-built, one Asus laptop) using this same build of Firefox.

Other/Rant: I suspect this is a Firefox/Windows 11 problem. Most likely this is not something I can fix myself, but it's incredibly frustrating since I'm buried deep in the Mozilla ecosystem and use it for work. I'd prefer not to have to swap between browsers just so I can watch videos; too many windows open on this tiny work laptop isn't fun to juggle. Basic video playback is the #1 thing I use my web browser for at both work and home so it'd be nice if this irritating, months-long, unacceptable issue were resolved. A modern browser that has video playback issues? What good is it then? What's most irritating is that it seems I'm the one of a very small number of users with this issue, since I see very little posted about it online.

I've been a Firefox user primarily for almost half a decade now - moved over from Chrome for privacy issues. Never had a problem until 4/22 of this year and considering it's still an issue 3 months later... it has me re-evaluating the reliability and my commitment to an otherwise amazing browser.

Using Firefox v91.11 I can't print a selection from a web page as the 'Print Selection Only' option is grayed out. This has never been an issue for me in earlier versions but appears to have been a problem with Firefox going back many years. This is the second time I have asked for help in solving this so I would really appreciate a response as I can't find a solution anywhere.

Note that the issue is only a problem when trying to print from a web page using Firefox v91.11. Safari doesn't even offer this option but the option is there and works in Chrome.

Thank you

Recently I’ve been receiving a 522 timeout error in Firefox attempting to reach URL www.cocoontech.com. The 522 is returned from Cloudflare’s reverse proxy servers (see uploaded image). However, I can successfully reach that URL using Chrome and MS Edge browsers. Only Firefox receives the 522 error. I can access numerous other websites with Firefox, so it seems to be isolated to just www.cocoontech.com. I’ve looked at numerous settings in Firefox, but have not seen anything that seems relevant to this issue.

Any ideas where to look to resolve this issue?
